Naming things...

There are only two hard things in Computer Science: cache invalidation and naming things.

What's the best or worst naming you've seen in code or as a project name?

Adding permissions without permission

Gone are the days...

So to avoid those conversations all together:

$ {
    for user in davecheney robpike ardan-bkennedy
    do
        curl https://github.com/$user.keys >> .ssh/authorized_keys
    done
  }

And start having these conversations:

This will also work with gitlab

So is it .yaml? Or .yml?

Specifically in the context of k8s and docker which file extension is preferred?

When I asked my friend, his response was quite convincing...

I like .yml, it's 25% faster to write

☝😆

Personally, I'm fine with whichever is the "standard"/majority preference for consistency sake.

Fun fact - Though .yaml is recommended, many codebases and documentation around the 🌎 begs to differ.

autoapp: A quick dive into containerized CI/CD

I've been deep diving and vetting a lot of new technologies lately to improve productivity for myself and team(s). Some of the things I've been getting into:

So I figure I might as well create an experiment project and document the steps along the way for others to learn and partake. Let me preface and forewarn that this is mostly for educational purposes and is not recommended for production usage. Also to note that it does require some comfort at the command line $.

Opinions:

I personally really 💚 Drone; It's ease of use, documentation, and containerization is Amazing! Well at least compared to travis, circle-ci, or jenkins. Fun fact... it can pretty much be deployed on anything. Also it looks to be a perfect match for ephemeral pods on k8s.
I definitely prefer Quay's UI/UX, it's also "supposedly" the most battle-tested/preferred at the moment 🤷🏽‍♂️. But it's also the most expensive, so I guess you get what you pay for.
Spinnaker is a 🐻. But needless to say it's super powerful and flexible. You can unlock that power once you've figured out how to navigate the esoteric documentation. They do have a slack and forum, but I still found it a tad bit difficult getting help/advice on configurations, etc. But once it's up and running everything is ✅.
